Systems, devices, and methods for analyte monitoring

Abstract

Systems, devices and methods are provided for inserting at least a portion of a sensor for sensing an analyte level in a bodily fluid of a subject. In particular, disclosed herein are various embodiments of reset tools for resetting an insertion apparatus, and containers for storing an analyte monitoring assembly. The analyte monitoring assembly can be a combination of components used for monitoring an analyte of the subject. The containers described herein can be used to load an analyte monitoring assembly into an insertion apparatus. The insertion apparatus can then be used to insert at least a portion of the sensor into the subject's skin. The insertion apparatus can be reusable.

         39 . A reset tool for resetting an applicator, the reset tool comprising:
 a shaft comprising a hollow interior;   a spring-loaded plunger configured to telescopically slide relative to the shaft, the plunger further configured to be inserted into a channel of the applicator; and   a tip portion configured to extend into a channel of a sharp carrier of the applicator, wherein   the reset tool is configured to advance in a distal direction into the applicator in response to a force, wherein the plunger is further configured to drive the sharp carrier towards a device carrier of the applicator until a portion of the device carrier engages with the sharp carrier, and wherein the shaft is configured to drive a sheath of the applicator in a distal direction upon the portion of the device carrier engaging with the sharp carrier.   
     
     
         40 . The reset tool of  claim 39 , further comprising a compressible spring housed within the hollow interior of the shaft. 
     
     
         41 . The reset tool of  claim 40 , wherein the plunger is further configured to collapse within the shaft and compress the spring, and wherein the compressed spring is configured to drive the shaft in a proximal direction. 
     
     
         42 . The reset tool of  claim 41 , wherein the compressed spring is configured to have a first force that is greater than a second force of a spring within the applicator. 
     
     
         43 . The reset tool of  claim 39 , wherein the shaft comprises a first cylindrical section and the plunger comprises a second cylindrical section, wherein a diameter of the shaft is greater than a diameter of the plunger. 
     
     
         44 . The reset tool of  claim 39 , wherein the shaft further comprises a handle and a cap, wherein the cap is configured to cover a top portion of the handle. 
     
     
         45 . The reset tool of  claim 39 , wherein the tip portion comprises a stepped cylindrical section, and wherein a diameter of the tip portion is smaller than a diameter of the plunger. 
     
     
         46 . The reset tool of  claim 39 , wherein the applicator comprises a spring, and wherein the spring of the applicator is configured to recompress in response to the sharp carrier driving towards the device carrier of the applicator. 
     
     
         47 . The reset tool of  claim 39 , wherein the applicator is configured to insert at least a portion of an analyte sensor into a skin of a subject. 
     
     
         48 . The reset tool of  claim 39 , wherein the tip portion comprises lead-in chamfers. 
     
     
         49 . The reset tool of  claim 39 , wherein a proximal end of the plunger comprises a rim configured to retain the plunger within the shaft. 
     
     
         50 . The reset tool of  claim 39 , wherein the channel of the applicator comprises an aperture configured to extend from a top portion of the applicator and axially align with the device carrier and sharp carrier. 
     
     
         51 . The reset tool of  claim 39 , further comprising a removable plug configured to seal the channel of the applicator from contaminants when the reset tool is not in use with the applicator. 
     
     
         52 . The reset tool of  claim 39 , wherein the shaft further comprises a cap, wherein the cap comprises a bottom portion configured to extend into the hollow interior. 
     
     
         53 . The reset tool of  claim 52 , further comprising a compressible spring housed within the hollow interior of the shaft, wherein the spring comprises a first end and a second end, and wherein the bottom portion of the cap is further configured to interface with the first end. 
     
     
         54 . The reset tool of  claim 53 , wherein the second end is configured to interface with a proximal end of the plunger. 
     
     
         55 . The reset tool of  claim 54 , wherein the spring is configured compress and decompress a distance between the cap and the plunger. 
     
     
         56 . The reset tool of  claim 52 , wherein the cap is removable. 
     
     
         57 . The reset tool of  claim 39 , wherein the tip portion is configured to form a friction fit with the sharp carrier. 
     
     
         58 . The reset tool of  claim 39 , wherein the reset tool is formed from a plastic material.
